This looks like a nitrogen deficiency. Here are some management tips to avoid this: https://www.plantvillage.org/en/topic....

Based on your photo I would recommend planting something to cover and protect your soil or adding a mulch layer so that soil and nutrients are not lost when it rains.

Which cover crop you grow depends on your soil, history of the field, and climate. I would recommend a nitrogen fixing cover crop to provide more available nitrogen to your field while building your soil health.

I think it is not a nitrogen deficiency. It could be viral disease. How many plants are infected in your farm? Is there any insect pests on the plant? And is there any symptoms on stem/leaf stalks? Also, it will help us if you upload some more close up images of infected leaves.

Thanks Dr. Ravishankar, i have around 200+ papaya plants, and i have noticed only two plants with that problem. Will take more pics once i visit the farm over the weekend( will upload close up images of the stem and leaves as suggested. Thanks for the link on nutrients and deficiency.

What is important is a close observation of the plants and other plants that may begin to show symptoms in the coming days. This might help distinguish between virus vs nitrogen deficiency. Can you do a soil test? Are you anywhere near a lab for a viral test?

@David Hughes, thanks for your reply and suggestions will surely do a close observation of the plants. Unfortunately am no where near a lab for viral test, but i can arrange for soil test.
